Hi there I'm working on our research project, ethanol from mandarin orange peels. According to some studies I need to hydrolyze because it is a lignocellulosic biomass. However I was wondering if there is another pretreatment that does not involve hydrolysis because it seems very risky and expensive. I tried finding other studies in the internet but I can't seem to find one. If you know that it is possible ,or if it isn't, please do tell. Thanks and have happy surfing.
